testNG+httpclient接口测试（eclipse+idea）

1. 环境，平台

 1.1 JDK1.7+eclipse

首先在eclipse安装testNG插件，安装过程http://www.blogjava.net/qileilove/archive/2014/09/02/417593.html

 

在网上下载httpclient4.3jar包，下载地址 http://download.csdn.net/detail/u010627840/8192601

下载JSON相关jar包，下载地址  https://mvnrepository.com/artifact/com.alibaba/fastjson/1.2.62

1.2 maven+idea+testNg 

依赖的jar

  org.testng
  testng
  6.8

  org.apache.httpcomponents
  httpclient
  4.3




  com.alibaba
  fastjson
  1.2.62

 

 

2 目的

 模拟浏览器发出get请求，获取返回的JSON，并解析。
